About: Esteban has been around for awhile, and he’s had a tiring life.

He started out as a lab animal, with humans constantly testing out products on him and his friends. Sometimes those products would turn out to be harmful, and Esteban would end up sick, or in a lot of pain.

Eventually the research facility shut down, and they didn’t have any need to keep Esteban and the other monkeys around anymore. They decided to kill them.

Luckily, Proyecto Caraya heard about their plan in time, and the staff was able to save all of the lab monkeys from an early grave. By the time Esteban got to the sanctuary he had been through a lot of trauma, and he is ready for a quiet life.

Monkey Rehabilitation

Proyecto Caraya is the first and only primate rehabilitation center in Argentina, and the only one in the world that works with black howler monkeys.
